When you go to Xi'an, you must go to Shaanxi Expo. There are many precious cultural relics in it. Follow the commentator Xiao Liu to see the history behind the cultural relics. It is very moving. Miss sister brought a book and showed us Douyin. She was very attentive and let us see the love of Xi'an people for their hometown. If you have the opportunity in the future, I will go to Shaanxi Expo and find Miss Sister to listen to history ~
